Referring in detail to the draw ngs 7 my improved heating apparatus (301111911885 3, hot air radiator manifold consisting of an outer end casing 2, an inner end casing anda plurality of conductor pipes, respecitlvelyflndicated at 4:, 5, 7, 8 and 95. I Th casing 2 an structure 18. The latter includes a frontwall "1930. Serial no."4'a4, 5a0.- V

arepreferably rectangular in transverse cross sectionto, afford greater radiatin'gflsurfacey but it is obvious that the contour; ofthe saiidl casings and conductor pipes may be, varied. to". best meetaconditions found in practice. 7 The .outer end casing 2 is. disposed veritically' and provided with a pa'irof transversely extending partitions 10., which divide the casings into three separate compartments, respectivelyindicated at 11,12and 13. The inner end casing3 is likewise disposed vertically and provided with a transversely,

extending partition 1 1, which: divides the casing 3 into two'separate compartments, indicated at and-16; .1 I

The casings 2 and 3 are each provided with a plurality of opening flanges- 17,twoof which. respectively establish communication with each of the compartments '11, 12, 13, 15 and16. The ends of theconductor pipes 4, 5., 6., 7, ,8- and 9 overlap and are attached'to respectivepopening flanges 17 in the followmg arrangement: The outer ends of the conductor pipes 4: and, 5 communicate with the casingcompartment 11; the outer ends of the conductor pipes 6 and 7 communicate with v the casing compartment. 12 and 5 the outer ends ofthe conductor pipes Sand 9 communicate with the casing compartment 13. In like manner, the inner ends of the conductor pipes so ,2 5 and 6" communicatewith the casing com-,

partment' 15, and the inner ends ofthe con-' 7 ductor pipes 7 and 8 communicate with the casing compartment 16; i

A furnace structure 18, providing a com bustion chamber 24;, is joined 'with the'inner end ofthe radiator manifold 1, and encloses the compartment casing 8, which virtually constitutes the inner wall of the furnace 19, sidewalls 29 and 21, and abottom 22. The

whic -isms with a s a k 0 h mney er stimulating combustion and ultimately dissipating the products of combustion.

A burner element 27 of any suitable construction is mounted in the combustion chamber 24, and it is obvious that the latter may be constructed to accommodate'the same to V the use of any kind of fuel.

A. vertically disposed partition wall 28,

mounted in the combustion chamber 24, is

fixedly dloami upp9 t cl by. the

furnace side wallsand 21. The partition Wall 28 extends transversely through the com- 1 bustion chamber 24 and has its upper end spaced from the top 23aof t1he lat-ter.- The partition wall 28 is disposed adjacent to the inner end casing 3, thereby providing a pas sage 29 therebetween. V The lower end of the latter communicates with the inner end of the combustion pipe 9, as indicated at The conductor pipes '4, 5, 6,7, 8 and 9 have their respective side walls disposed on the same vertical plane and are superposed relatively to each other, in the sequence enumerated. .The conductor pipes 4, 5, 6, 7, 8 and 9, While extending approximately in a horizfontal direction, are disposed angularly to incline slightly from the horizontal position, and the angular. disposition of any of the conductor pipes is directly opposed to the an 1 gular disposition of the conductor pipes adjacent thereto. I

The conductor pipes 4, 6' and 8 are disposed parallel to each other and incline toward the furnace structure 18, while the alternate conductorpipes 5, 7 and 9 are disposed parallel porting the device in spaced relation to the floor on which it rests.

. It will be apparent, that the casing compartments 11, 12,; 13, 15 and 16 merely constitute inter-communicating passageways for suitably connecting the associated conductor pipesto provide a continuous uninterrupted passage from the combust on chamber 24 to thefiue pipe 26. V

In the operation of my improved heating apparatus, the products of combustion travel through the radiator manifold 1,-as clearly indicated by arrows. bustion from the combustion chamber 24 pass downwardly through the combustion chamber passage 29 and outwardly through the lowest conductor'pipe 9, throughthecOmpartment 13, inwardly through-the conductor The products of com pipe 8, through the compartment 16, out= wardly through the conductor pipe 7, through the compartment 12, inwardly through the conductor pipe 6, through the compartment 15, outwardly through the conductor pipe 5, through the compartment 11, and inwardly through the top conductor pipe 4, from where it is dissipated through the fiue pipe 26 in a stack or chimney.

-. T Purpose f t Pa tit n Wall in the combustionchamber24,-is to direct the travelofthe products of combustion from the burner element 27 against the furnace top 23, which constitutes an end portion of the conductor pipe 4. As this portion of the latter communicates with the flue pipe 26, it is essential'for efficient performance that the same be maintained ata'hightemperature to promote proper draft action through the radiator manifold 1 an'd'zto'consume all material prod-' nets of combustion. i.

Theipartition wall 28 further serves to direct the products of combustion against the inner end casing 3 of the radiator manifold l, as the said products of combustion travel downwardly through the passage 29. thus heating the casing 3, the products of combustion, on passing through the radiator manifold 1, will be maintained at a high heat ing temperature and will be accelerated in their travel throughthe latter, whereby the products of combustion within the radiator manifold 1 will be of the most" efficient heating temperature.

It will here be noted. that the arrangement, configuration and number of conductor pipes embodied in my improved apparatus,=maybe widely varied to best meet any conditions found-in practice: Further, the construction of thezrcombustion chamber 24 and burner element 27 maybe such as to rendertlie same adaptable for the consumption ofcoal, oil, gas or any other fuel.

T he radiator manifold l-ispreferably constructed from sheet material .and of a metal best suited for heat radiation. The device may or may not be enclosedin a jacket depending upon whether the same be utilized for local or remote heat distribution. A feature of the present invention resides in the angular disposition of the conductor pipes 4,5, 6, 7, 8 and 9, in the manner stated, whereby the travel of the products of combustion therethrough is constantly upward'with out untoward natural resistance as when at tempting toforce or drawthe productsof combustion downwardly-against its natural flow by draft action or any other means.

The present invention provides a most efiicient heating apparatus, having a relativelyhigh heating capacity on maximum-fuel consumption. L f 1 WhatI claimisi Q a n 1.
